SQL injection is a type of cyber attack in which an attacker injects malicious code into a website's SQL database through a vulnerable input field, such as a login form or search bar. The attacker can then use this access to steal sensitive information, manipulate data, or even take control of the entire website.

For example, consider a website that has a login form that takes a username and password as input. The website's server then uses this input to query the SQL database to check if the provided credentials match those stored in the database. However, if the input fields are not properly validated and sanitized, an attacker could enter malicious SQL code into the username or password field, such as:

This code would cause the server to query the database with:

Rainbow Cipher: A Fictional Encryption Algorithm

Posted on MARCH 1, 2004 inTechniques

In the world of cryptography, it's essential to have secure methods for transmitting sensitive information. With the increasing use of technology and the internet, the need for safe communication has become more critical than ever. One of the oldest and most used methods of encryption is the use of ciphers. A cipher is a mathematical algorithm that transforms plaintext into an unreadable form known as ciphertext. In this article, we'll introduce you to a fictional cipher algorithm called the Rainbow Cipher.

How the Rainbow Cipher Works

The Rainbow Cipher is a fictional encryption algorithm that assigns different colors from the rainbow to each character of the plaintext message. The algorithm uses a simple substitution method to encrypt the message. The colors Red, Orange, Yellow, Green, Blue, Indigo, and Violet are used to represent the characters A to Z in the plaintext message. The ciphertext is generated by concatenating the color codes for each character of the plaintext message.
